django - 从 HTML

发布于 2024-10-14 15:37:34 字数 330 浏览 1 评论 0原文

我看过一些关于如何从 Django 中的 HTML 语句收集数据的文档，但对我来说都不是很清楚。有人有一个真实的工作示例可以分享吗？

就我而言，我的模板文件中有类似这样的内容：

<select title="my_options">
   <option value="1">Select value 1</option>
   <option value="2">Select value 2</option>
</select>

views.py 中为了收集选定的值会做什么？谢谢你！

I've seen a couple of documents on how to collect the data from a HTML statement in Django but none of them were very clear to me. Does anybody have a real working example to share?

In my case I have something like this in my template file:

<select title="my_options">
   <option value="1">Select value 1</option>
   <option value="2">Select value 2</option>
</select>

What goes in the views.py in order to collect the selected value? Thank you!

如果是 GET 请求，则为 request.GET['my_options']。如果是 POST，则为 request.POST['my_options']。这将是一个字符串，"1" 或 "2" （或 "

无论哪种方式，最好使用 Django 表单框架可以省去编写 HTML 和清理返回值的麻烦。

通过 POST 管理数据

def yourView(request):
    # Use '.get('id', None)' in case you don't receive it, avoid getting error
    selected_option = request.POST.get('my_options', None)  

    if selected_option:
        # Do what you need with the variable

Django 中的表单可能有用的一件事是，如果您对 URL 进行 POST 或只是加载它，则可以做不同的事情：

def yourView(request):

    if request.POST:  # If this is true, the view received POST
        selected_option = request.POST.get('my_options', None)
        if selected_option:
            # Do what you need to do with the variables
        return render_to_response(...)

return render_to_response(...)

有 2 个 render_to_response 以防您需要做不同的事情如果视图刚刚加载或收到 POST 的情况。

通过 GET 管理数据

def yourView(request):
    # Use '.get('id', None)' in case you don't receive it, avoid getting error
    selected_option = request.GET.get('my_options', None)  

    if selected_option:
        # Do what you need with the variable

Manage data via POST

def yourView(request):
    # Use '.get('id', None)' in case you don't receive it, avoid getting error
    selected_option = request.POST.get('my_options', None)  

    if selected_option:
        # Do what you need with the variable

One thing that may be useful with forms in Django is to make different things if you make a POST to the URL or just load it:

def yourView(request):

    if request.POST:  # If this is true, the view received POST
        selected_option = request.POST.get('my_options', None)
        if selected_option:
            # Do what you need to do with the variables
        return render_to_response(...)

return render_to_response(...)

There are 2 render_to_response in case you need to do different things if the view was just loaded or receive a POST.

Manage data via GET

def yourView(request):
    # Use '.get('id', None)' in case you don't receive it, avoid getting error
    selected_option = request.GET.get('my_options', None)  

    if selected_option:
        # Do what you need with the variable
